ADM3485EARZ Description

Short technical summary and product information.

ADM3485EARZ is a 3.3 V low-power RS-422/RS-485 transceiver from Analog Devices. It is designed for half-duplex communication on multipoint bus transmission lines and complies with TIA/EIA RS-485 and RS-422 standards. The device operates from a nominal 3.3 V supply and supports data rates up to 12 Mbps.

 

The transceiver includes one driver and one receiver, with a receiver input impedance of 12 kΩ allowing up to 32 nodes on the bus. It features ±15 kV ESD protection on the RS-485 input/output pins, a common-mode input range of -7 V to +12 V, and a fail-safe receiver design for open-circuit conditions. The driver outputs are tristated when disabled or powered down, and a shutdown mode reduces power consumption.

 

The ADM3485EARZ is suited for industrial control, telecommunications, power/energy metering, EMI-sensitive systems, and local area networks. It is available in an 8-lead narrow SOIC package (8-SOIC, 0.154" width) for surface-mount assembly, and operates over an ambient temperature range of -40°C to +85°C. Typical supply current is 2.2 mA.
